Pump KNF N840.1.2 FTP
Pump KNF N840.1.2 FTP

The N series chemically resistant diaphragm pumps 840.1.2 are double head and operation devices dry used in a wide variety of applications for laboratories. They transfer and empty without contamination. The heart of these very compact pumps is a diaphragm structured KNF. This patented diaphragm was extremely optimized using the Finite Element method. As a result, we were able to obtain smaller pumps, but at the same time, with a longer life diaphragm
